Helfen Sie mir bitte zu überprüfen.

Answer 1

Sie verbinden Datenbank mit mysql-Treiber, aber fügen Sie mit mysqli-Treiber ein. Sie müssen so etwas tun.

<?php 

$con = mysqli_connect("localhost", "root", "batman", "database"); 
mysqli_query($con,"INSERT INTO Persons (FirstName,LastName,Age) VALUES ('Glenn','Quagmire',33)")); 
mysqli_close($con);
